timated income tax regulations will clarify the estimated income tax regulations under section 6654 of the Code. Removal of §§1.6015(a)–1 through 1.6015(j)–1 also alleviates any confusion under the current section 6015 regulations, which address relief from joint and several liability for an individual who has made a joint return. Adding §§1.6654–5 and 1.6654–6 will provide additional instructions for determining estimated tax payments and additional guidance for nonresident alien individuals required to make estimated tax payments.

Special Analyses

Because these regulations are interpretative and generally re-codify, under an existing statute, existing rules promulgated under a prior statute, notice and public comment procedures are not required pursuant to 5 U.S.C. 553(b)(A) and (B), and a delayed effective date is not required pursuant to 5 U.S.C. 553(d)(2) and (3). Because no notice of proposed rulemaking is required, the provisions of the Regulatory Flexibility Act, 5 U.S.C. 601 ( et seq .) do not apply. Further, because this Treasury decision is not a significant regulatory action for purposes of Executive Order 12866, a regulatory assessment is not required. Pursuant to section 7805(f) of the Code, these regulations were submitted to the Chief Counsel for Advocacy of the Small Business Administration for comment on their impact on small business.

Drafting Information

The principal author of these regulations is Tatiana Belenkaya, Office of Associate Chief Counsel (Procedure and Administration), Administrative Provisions and Judicial Practice Division.
